Energy Providers In Illinois

Updated: 11/10/2020

Find the Best Illinois Energy Providers

Energy deregulation in Illinois began in the mid-1990s with electricity and natural gas legislation that would allow energy customers to shop around for the supply portion of their energy bills. Most of the state is now deregulated, including the service areas of ComEd and Ameren, the state’s two largest public utilities.

Deregulation brought about Energy Choice via “retail energy provider” companies that compete with each other to supply energy to customers. No matter where your supply comes from, transmission and distribution is serviced and charged to you by your default utility, which is regulated by the Illinois Commerce Commission.

Select the Best Energy Provider for Your Needs

Switching energy providers is fast and easy, but there are several key factors that you should look for before choosing a new provider. Whether you are shopping for electricity or natural gas, be sure to ask:

  1. Is the energy provider regulated by the Illinois Commerce Commission?
  2. Is the energy provider’s rate lower than what you’re currently paying (the Price-to-Compare)?
    • The Price-to-Compare for both electricity and natural gas can be found on your utility bill. 
    • Electricity is expressed in “cents per kilowatt hour” (kWh), and natural gas is expressed in either “hundred cubic feet” (ccf) or “therms”. (To convert ccf to therms, multiply the ccf by 1.025).
  3. Does the provider offer low fixed rates?
    • Variable rates are subject to large fluctuations, while fixed rates lock in low prices for the duration of the contract.
  4. Is the length of the contract comfortable for you and your energy needs?
    • 3, 6, 12, and 18-month contract lengths are common.
  5. Are there any incentives or bonuses for switching?
  6. Are there any additional fees for early contract termination?

Researching all available retail energy providers is a daunting task, since there are dozens of electric and natural gas providers to choose from.
